Ridge Line II 27.5" Boost Wheels

Offering exceptional value, great performance and reliability, the Ridge Line II series are our feature packed entry level, Thru-axle and tubeless compatible MTB wheels.

With a 30mm internal and 35mm external width, the rim is well suited to most modern MTB tyres from 2.25 to 2.8”.  Tubeless compatible using a hooked bead profile also offers compatibility with traditional clincher tyres and inner tube if so desired.

Hand built with 32 no-nonsense plain gauge J-bend spokes and durable brass nipples front and rear into stainless rim eyelets, we have built these wheels to last.

At the heart of these wheels are our RL II series hubs in Boost MTB widths for Thru-axle frames and forks making them a no fuss option for modern trail riders.

The rear hubs also feature high-strength Cro-Mo axles and 4-pawl Cr-Mo HG type freehubs with excellent engagement.
